Open source Home automation

If you are an enthusiast and plan to select an energy meter for the open source home automation system you used(maybe home assistant,openHAB and NodeRed, etc..), IAMMETER is also a good choice.

Home assistant

IAMMETER supports many integration methods in the home assistant, such as core integration, Modbus/TCP, MQTT, and HACS.

Four methods to integrate the Wi-Fi energy meter into the Home Assistant

IAMMETER APP && Cloud service

If you want to find an energy meter with the full support of an APP and cloud service, you can also select IAMMETER (in fact, the IAMMETER-cloud service is one of the highlight feature of IAMMETER).

Energy management in the industrial area, such as a smart factory

If you have many places to be monitored and some of the places can be defined as tree structure (for example, place A can be set as a parent node with three child node, place A1, A2 and A3), you can define this kind of tree structure for all selected places on IAMMETER now, then you can get the comprehensive analysis and report based on this tree structure. So it is easy for you do the energy consumption monitoring or solar energy monitoring in a higher level for the whole structure of all places included.


Integrate into an on-premises solution

IAMMETE-cloud is a powerful energy monitoring system, especially for solar PV energy monitoring. But you may not want to use IAMMETER-cloud for some reasons. We have opened some APIs and provided some methods for you to develop your own energy monitoring system. For more details ,please refer to

Integrate into an on-premises solution

Besides this, you can also request the data from the energy meter every sec, by the Modbus/TCP.
